Tandem histone methyltransferase upregulation defines a unique aggressive prostate cancer phenotype.

ABSTRACT:

Background

Histone modifications alter transcriptional gene function and participate in cancer progression. Enhancer-of-Zeste-Homologue-2 (EZH2) and Nuclear-Receptor-Binding-SET-domain2 (NSD2) methylate H3K27 and H3K36, respectively, to regulate transcription. Given the therapeutic interest in these enzymes, we investigated expression and coregulation in hormone-sensitive (HS) and castrate-resistant (CR) prostate cancer (PC).

Methods

EZH2 and NSD2 levels were quantified using VECTRA analysis in HS and CRPC tissue microarrays (n = 105 + 66). Expression data from The Cancer Genome Atlas (n = 498), Memorial Sloan Kettering Cancer Center (n = 240), and Stand Up to Cancer/Prostate Cancer Foundation (n = 444) cBioportal datasets were queried, and associations between EZH2 and NSD2
